DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toll ticket issuing device that is installed at a toll road entrance or the like and automatically issues a toll ticket or the like on which the type of vehicle, etc., is written to the driver of an automobile.

Conventional technology Conventionally, this type of pass ticket issuing device was developed in 1982.
As stated in Publication No. 80871, there is a system in which a ticket is issued at one of multiple exits depending on the vehicle type. FIG. 1 is a device layout diagram of this conventional example, and FIG. 2 is a circuit diagram of the same conventional example for measuring the distance between wheels.

In Fig. 1, 50 is a vehicle, 51 and 52 are vehicle separators that distinguish it from other vehicles, and 53 is a wheel width L whose resistance value changes due to tire pressure, as shown in Fig. 2. Step board for detecting, 54, 55
5 is a vehicle height detector that detects whether it is a bus pattern or not.
6 is a ticket issuing machine, and 57 to 59 are ticket issuing ports. In Fig. 2, L is the wheel width, l is the tire width, a1 to c1, a2 to c2 are the measurement terminals, and r1 to
r6 is a resistance.

In FIGS. 1 and 2, when a vehicle 50 approaches the entrance, the wheel spacing, the number of axles, and whether it is a bus are detected by the treadboard 53, vehicle separators 51, 52, and vehicle height detectors 54, 55. Distinguish and decide the car model,
A toll ticket is issued from the toll ticket issuing machine 56. At this time, the pass ticket is issued from the issuance ports 57 to 59 at the upper, middle, or lower height depending on the vehicle type.

In this way, even in the conventional example, passes were issued from one of a plurality of issuing ports depending on the type of vehicle.

Problems to be Solved by the Invention However, in the above conventional ticket issuing device, as shown in Figure 2, two long resistance wires are buried in the road, a conducting wire is provided above the wires, and the weight of the tires causes the conducting wires to Since the distance between the wheels is determined by short-circuiting the resistance wire and the resistance wire, it is impossible to determine whether the vehicle has a single tire or not. There was a problem in that the system had to be discriminated and the cost of the entire device was high.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide an excellent toll ticket issuing device that can accurately identify vehicle types and is inexpensive.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a large number of switches arranged in a staggered manner in the cross-road direction at intervals sufficiently narrower than the width of the tires, and detects the passing of a vehicle by pressing the tires. a passage detection device that detects the passing of a vehicle when the light is blocked by placing a light transmitting part and a light receiving part at both ends of the road; A tread wheel control circuit that determines the number of axles and the number of wheels based on the continuous state of closure of these switches during one detection of the tread board, and a double circuit if these wheels are close to each other by a certain distance or more. The vehicle type is determined from the output signal of the tire recognition circuit and the above-mentioned tread logic circuit, and is recorded on the pass ticket. The system is equipped with a ticket issuing device that issues a ticket to the lower issuing port when the tire is determined to be a double tire, and issues the ticket to the upper issuing port when the tire is determined to be a double tire.

Effects According to the above configuration, the present invention determines the number of axles from the number of times the vehicle passes the treadle while the vehicle is being detected by the passing detection device, and determines the number of wheels from the continuous state of the switch being closed during one detection of the treadle. The system determines whether it has double tires or not, determines the vehicle type, and issues a ticket from the issuing port corresponding to the vehicle type, making it possible to accurately identify the vehicle type and eliminating the need for a conventional vehicle height detector. , the device can be constructed at low cost.

Example An example of the present invention will be described below. The driver's eye height of currently produced vehicles is roughly classified into three categories depending on the vehicle type.

Ordinary passenger car: 1200mm 4.25~10 tons truck: 1950~2200mm Shared buses, large sightseeing buses: 1950-1850mm moreover, Wagon car: 1550mm Small truck: 1700mm On the other hand, the length of the driver's arm is approximately 500 mm.

Figure 3 shows the results of actual measurements of the eye position, shoulder position, and vehicle window position of drivers of 11 different types of vehicles, as well as the reachable range when drivers put their arms out of the window. It shows. As is clear from Figure 3, if there is a ticket issuing port at a height of approximately 1200 mm or approximately 1800 mm, it is possible to issue tickets for most vehicles.

FIG. 4 shows a vehicle passage detection section of a ticket issuing device in an embodiment of the present invention. In FIG. 4, 1 is a vehicle passageway, 2 is a footboard, and 3a and 3b are a light transmitting section and a light receiving section, respectively. In addition, the fourth
In the figure, 4a _L and 4a _H are 500mm and 1500mm from the road surface among the many light emitting elements that make up the light transmitting section 3a.
This is a light emitting element installed at a height of . On the other hand, 4
b _L and 4b _H are light receiving elements provided at a height of 500 mm and 1500 mm from the road surface, respectively, among the many light receiving elements constituting the light receiving section 3b. 6 is a ticket issuing device, and 5a and 5b are issuing ports provided in the ticket issuing device 6. The issuing port 5a is installed at a height of about 1800 mm from the road surface based on the actual measurement results shown in Fig. 3. , and the issuing port 5b is provided at a height of about 1200 mm from the road surface.

FIG. 5 shows the circuit configuration of this embodiment. In Fig. 5, reference numeral 2 denotes a footboard, which has a sensing area of about 4 cmφ as shown in Fig. 6 a and b, and when pressed by the wheels, opens and closes the electric circuit as shown in Fig. 6 a. Sensors 11 having the function of performing this function are arranged in a staggered manner in the cross-road direction, as shown in FIG. 6b. As a result, ON/OFF signals from a large number of sensors constituting this treadle board 2 are applied to the treadle ring circuit 7. An example of the operation of the tire recognition circuit 8 will be described below.

Depending on the width of the tire, the content of opening and closing of the contacts in the treadle logic circuit changes. For example, in the case of a single tire such as a passenger car, three to four of the sensors shown in FIG. 6b are opened and closed by one wheel on one side. Moreover, 3 to 4 occur only in horizontally adjacent elements. With double tires, 6 to 8 tires are opened and closed in the same way. However, in the case of double tires, since there is always a gap between adjacent tires, one or two untrodden areas appear between six to eight tires. The tire recognition circuit 8 focuses on this point, assigns an address to each horizontal element arranged in a staggered manner, calls the corresponding address in order, and tests whether the contact opening/closing output is continuous. That is, in FIG. 6b, the footboard 2 is
Two sensors 11 with a diameter of 4 cm are arranged in a staggered manner at 8 cm intervals.
Since they are arranged in rows, the tire width can be detected almost continuously and accurately without any breaks. Therefore, when each tire has a width of about 30 cm, such as a double tire, and the gap between the tires on one side is about 5 cm, and the gap between the tires on both sides is about 160 cm, as described above, sensor 1's 6 In the middle of ~8 areas, 1~2 areas that are not stepped on appear on the left and right.

In this way, each sensor 11 is assigned an address, the corresponding addresses are called in order, and the continuity of the contact opening/closing output is detected by the tire recognition circuit 8. If so, it is determined that the tire is a double tire, and a signal is output to the C8 code generation circuit 10. Incidentally, if this recognition circuit is performed only while the passage of a vehicle is detected by the passage detection logic circuit 9, false detection by a person or the like will be eliminated.

On the other hand, the output of the step board logic circuit 7 and the output of the light receiving element of the light receiving section 3b are applied to the passage detection logic circuit 9, which outputs C ₁ to C ₄ codes as in the conventional example. 10 is a code generation circuit, and this code generation circuit 10 outputs "1" or "0".

Figure 8 shows the vehicle codes for double tire vehicles and other vehicles, and C ₈ for double tire vehicles.
The code will be "1" and the _C8 code of other vehicles will be "0".

The vehicle codes C ₁ to _{C 8} are input to the ticket issuing device 6 via the lane control device. In the ticket issuing device 6,
The _C8 code is determined, and if the _C8 code is "1", a ticket is issued from the issuing port 5a located approximately 1800 mm from the road surface. On the other hand, when the _C8 code is "0", a ticket is issued from the issuing port 5b located approximately 1200 mm from the road surface.

Effects of the Invention As is clear from the above embodiment, the present invention determines the number of axles from the number of times the vehicle passes the treadle while the vehicle is being detected by the passing detection device, and continuously closes the switch during one detection of the treadle. It determines the number of wheels and whether or not it has double tires based on the condition, determines the type of vehicle, and issues a ticket from the issuing port corresponding to the type of vehicle, making it possible to accurately identify the type of vehicle.Moreover, it does not detect vehicle height like conventional methods. Since no equipment is required, the device can be constructed at low cost.
